Field-effect transistors fabricated from carbon nanotubes have been investigated extensively over the past two decades. This study demonstrates a nanotube-based integrated circuit design that ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

This automatic battery-charger, built around a single transistor, starts charging when the battery voltage drops beyond a preset value and stops when once an upper preset voltage is reached.

Thus the three basic bipolar transistor circuit configurations have equivalents with a FET; common-emitter becomes common-source, common-base becomes common-gate, and an emitter follower becomes a ...

[Part 1 covers the basics of bipolar junction transistors and looks at some typical BJT audio circuit configurations.] 9.7 Junction Field Effect Transistors (JFETs) JFETs are, almost invariably, ...

The classification circuit works as follows: Transistors Q1, Q2, R2 and R3 form a 350 μA current source (set by the value of R3) that biases U1. Transistor Q3 and U1 form the current source that sets ...
